The acent end ofthe Walllhash flap 7 vf0jecti1gg therefrom adjacent the flai 4, h two flaps 'be ne s pe e a Slit 6 cut exte dingtc the .corner dof the body 01' bottoih 1 between the tt'ttlls z and 3 and wells to be cci rie de- 60 opposite direction at the basal portion of ..the doubled portion, whereby the bent back there is also a fold line 8 between the wall 2 I and base of the flap 7. 'The flap 7 is pro:

vided with a portion 9, which is'foldable back against the outer side of the body; por- -tion of the flap 7, upon the diagonal or oblique fold line 10 extending from the free end of the flap 4 to that side of the base of the flap 7 remote from the flap 4. That edge portion of the portion or supplemental flap 9 of the flap 7 which is remote from the flap 4, is provided with a recess or notch 11.

When the blank is cut or struck from the stock, the flaps 4 and 7 may be readily formedtherein, and it will be noted'that the flaps lie within the outline of the blank, in order that excessive or additional stock will not be required. This is of advantage, since i the Waste incident to ordinary corner fasteners is eliminated. The flaps 4 and 7 are then bent or folded to provide the interengageable portions or members carried by the adjacent'ends of the adjacent walls 2 and 3, and to this end the flap 4 is folded'backor H basalfportionof the flap 4 and the wall 3 reflexed against the inner side of the wall 3 parallel therewith, and a staple or other securing element 12 is engaged through the between the side edges of the said flaps.

The staple or securing means 12 therefore holds the flap 4 in place adjacent the inner side of the wall 3 of the box with the flap 4 V, projecting inwardly orv away from the respective end ofthe wall 3.

The portion 9 of the flap 7 is folded back against the outer side of the body portion of the flap 7, upon the fold line 10, the body portion of the flap 7 and the portion 9 being offtriangular contour and coinciding when V (flap provides the other side of the said. pocket the outer side of the pocket or porthey are folded together, and a staple or securing element 13 is then drivenor engagedthroughthe body portion of the flap .7 and the portion '9 of the said flap adjacent the apices of the said portions. Thus, the

portions of the flap 7 will be secured or held together, and will 7 provide a triangular pocket 14 whose mouth is disposed adj acent the end of the wall 2 and which pocket opens outwardly and away from the wall 3 of the box. It will be noted that the body portion of the flap 7 provides the inner side of the pocket 14, while the portion 9 of the said tion 9 having a recess or notch 11 adjacent and extending away from the mouth of the pocket.

The doubledport ion 7 -9 which is located at the inner side of the wall?) projects angu larly in one direction from the wall 2, and is provided with the pocket 14 opening in the flap 4 at theend of the wall 3, which is located at the inner side of said wall, by fitting in said pocket, will thereby hold said walls against separation and outward movement, the flap 4 projecting in the same di-' rection as the doubled portion} Particular attention is directed to the fact that in the present device, the portion or side 9 of the pocket 14 is provided withaprojection or extension 15 which emer ing combination with or which cooperates with the other parts ful results.

The parts are thus secured togetherby the to accomplish new and usei staples or securing means 12 and- 13 at the 3 factory, and the box may'still rremain in blank form,"i1i order that the blanks may be i stacked or bundled-as usual, without requiring the boxes to be erected before it necessaryor desirable to use them. f I

'With the parts secured together as illustrated in Fig. 3, and as above described, the

side walls 2 and 3 of the box maybe re ly and efl'ectively secured or locked together for holding thewalls2 and 3' together in'a" firm and eflicient manner; To attach the.

side walls 2 and 3 together, they are folded upwardly at an angle to the bottom -1, and the parts are properly: manipulated to insert the refiexed or bent back l'lap; 4 into the pocket 14, whereby the pocket which is bent inwardly will snugly receive the flap or" tongue4 and rest against the inner side of the wall 3. The flap 4 is engaged within the pocket 14 by swinging the wall 2 inward toward the bottom 1 afterthe wall3 has 7 i been" swung to erectjposition' perpendicular V with the bottom 1, and which will bring the pocket 14 to such a position adjacent or be yond the free portion of the fiap4, to allow 7 the flap 4' to be readily received'by' "the pocket 14 when the wall 2 'is swung back to upright or erect position. The recess or notch 11 of the portion 9 will receive "and accommodate the 'stap'leor securing element 12, while the cut away portion '5 of the flap 4 will prevent the flap4ffrom interfering box, when the sidewalls 1 v erted against the sidewalls of 'thelbox. Q

Since the pocket 1410f the side wall2 is I engaged over the flap 4 of the wall 3 with the portion 9 projecting between the'flap 4- and w all-3 beyond the staple 12, the'lwall 2 cannot swing outward, and since the flap 4 of thewall 3 is received in the pocket14 of the wall 2,'the wall 3 cannot swing outward, and as aconsequence, the interengagement of the members ofv the walls 2 and3 7' will efliciently hold the walls'again'st separation, and the parts will not be liable toftear; loose, as is frequently the case with the ordinary fasteners of clothing and similar boxes. Especial attention is directed to the fact that when the box is erected, the pocket 14: being bent or swung inwardly, to the position illustrated in'Fig. 5, will cause the prothe flap a and pocket 14 may be interengaged. WVhen the flap 4 andpocket 14 are interengaged and the walls moved to proper position perpendicular with the body or bottom 1, the projection or stop 15 will spring back to normal position against the wall 3 and will thereby hold the pocket 14 in position, and will prevent the pocket 1 and the wall 2 from swinging inwardly, so

as to prevent the pocket from disengaging the flap 4. As a result of the provision of the projection or stop 15, the etficiency and utility of the corner. construction is enhanced considerably, and the adjacent Walls 2 and 3 cannot be accidentally detached and 7 can only be detached by manually swinging the projection or stop 15 inwardly so as to allow the pocket 14 to be moved inwardly out of engagement from the flap 4.

From the foregoing, taken in connection with the drawing, the many advantages and capabilities of the present invention will suggest themselves to those versed in the art and further comment is deemed unnecessary.

Having thus described the invention, what is claimed as new is 1. In a device of the character described, a body having adjacent walls, one wall having a doubled portion at the inner side of the other wall and projecting angularly in one direction from the first mentioned wall, and said portion having a pocket opening in the opposite direction, the second mentioned Wall having a portion at its inner side proj ecting in the same direction asthe first mentioned portion and adapted to fit'in said pocket, whereby the walls are thereby held against separation and outward movement, the first mentioned portion having an extension seating against the body for holding said portions in engagement with one another.

2. Ina device of the character described, a body having ad acent walls, one wall having a doubled fiap at one end and at the inner side of the other wall and projecting angularly in one direction from the first mentioned wall, said doubled flap providing a .pocket opening in the opposite direction,

the second mentioned wall having a portion bent back from one end and located at the inner side thereof, said portion projecting in the same direction as the doubled flap and being adapted to fit in said pocket, whereby the walls are thereby held against separation and outward movement, the free portion of said flap having an extension seating against the body for preventing the inward movement of the doubled flap.

In testimony that we claim the foregoing as our own, we have hereto afiixed our signatures in the presence of two witnesses.
